What is a geek?

My friend John posted a great picture on his Tumblr account the other day: a map of geek culture.

So, what’s the subject matter we could cover on Geek-Speak? Looks like a pretty wide range of ideas to me! :)

Is there anything in particular you’d like to see covered though? Any subjects you want to take a closer look at, or any questions you want answered? Please let me know in the comments or via the contact form and I’ll do my best to accommodate!
